I promised to show you some of my favourite faces for the heroes in my stories, so here goes. This one (left) doubles up as Finlay in Banners and Dark Pool except that Finlay's hair is black rather than brown.
The face matched the character I had dreamed up so very well. I don't know the actor, and I don't think I've ever seen him in a film, but I don't need to.
I already have the vague outline of the character in my imagination so when I'm trawling the net, reading posts, or just scanning a magazine, sometimes I'm lucky and see a photo that clicks with the image in my head - bingo! There's recognition. I capture the pic and then I can look at it, study it, decide how best to describe it in words that will carry a picture to the reader. The sad thing was that by the time I found Finlay's "picture" he was already in print.
